Abstract
According to one embodiment, a display device includes a first polarizing element, a second polarizing element, and a light-modulating layer located between the first polarizing element and the second polarizing element, each of the first polarizing element and the second polarizing element includes a guest-host liquid crystal layer and a control electrode in an active area including at least one sub-area, the guest-host liquid crystal layer including dye having anisotropy in absorptive power for visible light, the control electrode controlling an alignment direction of the dye in the sub-area.

A display device comprising:
- a first polarizing element;
- a second polarizing element;
- and
- a light-modulating layer located between the first polarizing element and the second polarizing element,
- each of the first polarizing element and the second polarizing element comprising a guest-host liquid crystal layer and a control electrode in an active area including at least one sub-area,
- the guest-host liquid crystal layer including dye having anisotropy in absorptive power for visible light,
- the control electrode controlling an alignment direction of the dye in the sub-area.
A display device comprising:
- a first polarizing element comprising first dye having a first long axis;
- a second polarizing element comprising second dye having a second long axis;
- and
- a display panel located between the first polarizing element and the second polarizing element,
- the display device having a display mode in which the first long axis and the second long axis intersect each other in a main surface of the display device, and a transmittance mode in which the first long axis and the second long axis are parallel to each other and intersect the main surface.
